Abstract (en)
[origin: EP1093850A2] Provided are a packed column arranged so as to be capable of effectively preventing polymerization of a polymerizable compound such as a (meth)acrylic acid in treating the compound, and a method for treating a polymerizable compound using the packed column. The packed column, which is provided with a packing support plate and is filled with a packing on the packing support plate, is arranged so as to include a packing layer (B) having a greater percentage of voids than that of a packing layer (A), between the packing support plate and the packing layer (A). <IMAGE>
